4 Claims. (Cl. 156-14) The invention relates to a window screen, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the introduction between double windows of a removable screen mounted on a sash slidable in the window frame, as pointed out in the claims for novelty following a description in detail of the construction of the frame and screen element in relation to the window glazing.

The objects of the invention are to effect economy in the original construction and in the maintenance of the screen parts, andat the same time insure comfort for passengers and persons in trains and other places and to insure ready removal for cleaning purposes, which is particularly useful in the use of this screen in railway cars, for which it has been specially designed, and

generally to construct a screen that will in the first place meet the requirements of railway car builders and yet be adaptable to other structures.

In the drawings, Figure 1 is a perspective view of the screen element attached to the sash.

Figure 2 is a vertical sectional view on the line 22 in Figure 1.

Figure 3 is a cross sectional view on the line 3-3 in Figure 1.

Figure 4 is a cross sectional view on the line 4-4 in Figure 1.

Figure 5 is a cross sectional view of the screen element mounted in a window frame midway of the height of the glassand the screen.

Figure 6 is a cross sectional view of the screen element and window frame showing the screen locked to its open position.

Figure 7 is a detail showing a modification of a means for attaching the screen to its sash.

Figure 8 is a fragmentary sectional view showing the modified means for attaching the screen to the sash, illustrated atiright angles to the fragmentary view shown in Figure '7. v

Figure 9 is a fragmentary detail of the screen, and screen frame showing a hook for drawing down the screen.

Figure 10 is a fragmentary detail of the binding member.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the numeral 15 illustrates a middle sash having the vertical guard slots 16 and 17 and the bevelled surface 18 on the inner side of the upper bar.

The lifting slot 19 is made centrally in the from the influence of disturbing particles.

lo-wer bar in the customary manner, sometimes with the frame 20, while the bar 21 is attached for pulling the sash to its closed position.

The screen 22 is formed with a binding 23 or binding member 231) as it may be called, and 5 this binding is inserted in the pockets formed by the plates 23a secured to the sash bars by the screws 24 and from the binding 23, the finger grips 25 and 26 project upwardly so that the screen may be lifted out for cleaning purposes. This screen is attached to the sash opening below the bevel 18.

The spring latch lock 27 is shown as projecting from the plate 28 near the lower'end of the sash 15 at one corner, and is used for the purpose 15 of holding the'screen to its extreme open position when not in use. I

The window frame 29 is formed with three sash grooves 30, 31 and 32 on either side and is secured to the posts 33 and 34, each groove having the flanges 35, 36 and 37 inwardly turned into corresponding guard slots in each sash, the sashes 38 and 39 being introduced in the grooves 30. and 32, while the sash 15 is introduced in the grooves 31. Thus the screen is between the panes of glass in the sashes 38 and 39 and spaced therefrom.

In Figures '7 and 8, the rivet heads 40 are shown as replacing the plates and in this construction,

' the screen frames have the slots 41 narrowing to the slots 42 for the purpose of binding or clamping the screen frames tightly to the sash bars against the rivet heads which are rigidly secured to said sash bars.

This is only a modification of the invention to show how the removal of the screens may be facilitated for cleaning purposes.

In the operation of the invention, the screens installed between two window panes enable the. passengers in travelling in railway cars to open both the outside window and the inside window and as the screens afford protectionfrom the cinders and dust, the passengers safely enjoythe cool air. The flanges of the grooves enteringthe slots in the sashes protectthe screen, as well as the windows when partly open from the trouble of cinders, but the screen itself is of course the important member, and this being attached to the middle sash enables the passenger to screen the opening effectively so that he is practically free The screen when not in use may be slid up to the top of the sash and there latched.
